The 'Lens Flare' effect simulates optical phenomena caused by bright light in a camera's lens system. Lens flare has many controls, which allow for a wide variety of different effects. Several program modules utilize this effect:
Lens flare particle effect (described below in detail). Particles define the position of flares.
Lens flare of a camera object. Light sources, which illuminate the camera, create lens flares.
Image Flare effect. Flares are added to the brightest areas of the image.
The lens flare controls are divided into three tabs.
Ring color: The color of the thin ring around the central glow.
Ring size: The diameter of the ring (1.0 is the same as image width). Set to zero to remove the ring.
Ring thickness: The thickness of the ring.
Random seed: Selects a sequence of random colors and sizes for the flares. Each seed value produces a completely different looking flare sequence.
Size: The maximum diameter of sub flare rings.
Regular & Random Angle: Defines the orientation of streaks. Changing the value rotates the streaks (which naturally can be animated).
Random Speed: The random streaks appear and fade away in animations, creating an impression of light radiation. This control defines how quickly the streaks change. Value zero freezes the random streaks to be static.
